Abstract
PURPOSE: The titled adhesive that is prepared by adding an organic solvent to a phenol-modified liquid amino resin resulting from copolycondensation between a liquid amino resin and a liquid phenol-formaldehyde resin, thus showing improved adhesion to resin-rich wood materials.
CONSTITUTION: A liquid amino resin and a phenol-formaldehyde resin resulting from the reaction between 1mol phenol and 2.5W4.0mol formaldehyde under a basic condition are mixed or subjected to copolycondensation to prepare a liquid phenol-modified amino resin. (A) The resultant modified amino resin (100pts.wt.) is mixed with (B) an organic solvent that softens or dissolves the resin included in the wood such as ethanol (2W20pts.) to give the objective adhesive.
USE: It is suitably used in the production of plywood laminates.
